DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0023] Embodiment one:

[0024] Please refer to Figures 1 to 4 The utility model provides a kind of technical scheme: a formwork support frame for highway bridge construction, including vertical rod 1, vertical rod 1 is fixedly connected with connecting disc 4, connecting disc 4 is movably connected with horizontal rod 2, and the both ends of horizontal rod 2 are fixedly connected with straight plug 3, and straight insertion groove 401 is opened in connecting disc 4, and straight plug 3 is movably installed in the straight insertion groove 401 of connecting disc 4, further include locking piece 5, and locking piece 5 includes mounting disc 501, first sliding sleeve 504, second sliding sleeve 505, locking rod 506 and movable rod 508.

[0025] Mounting disc 501 is fixedly connected on vertical rod 1, and mounting disc 501 is located at the position below connecting disc 4, first sliding sleeve 504 and second sliding sleeve 505 are movably installed on vertical rod 1, locking rod 506 is fixedly connected on first sliding sleeve 504 and second sliding sleeve 505, movable rod 508 is movably installed in mounting disc 501, and the lower end of movable rod 508 is fixedly connected with first sliding sleeve 504 and second sliding sleeve 505, and locking rod 506 is movably installed with straight plug 3.

[0026] Further, locking piece 5 further includes back hook 507, back hook 507 is fixedly connected at the position of one end of locking rod 506, locking groove 301 is opened in straight plug 3, locking rod 506 is movably installed in locking groove 301, and back hook 507 can movably pass through locking groove 301.

[0027] The hook 507 is located at the upper end of the locking rod 506, and the hook 507 passes through the locking groove 301 of the straight plug 3. The natural falling of the first sliding sleeve 504 and the second sliding sleeve 505 will make the hook 507 fall, so as to be clamped at the side of the straight plug 3, so that the locking rod 506 is not easy to slide off.

[0028] Further, the locking piece 5 further comprises a positioning ring 503 movably installed on the vertical rod 1 and located between the mounting disc 501 and the connecting disc 4. The positioning ring 503 is fixedly connected with the movable rod 508. The locking piece 5 further comprises a movable groove 502 formed in the mounting disc 501, and the movable rod 508 is movably installed in the movable groove 502 of the mounting disc 501.

[0029] One side of the mounting disc 501 limits the maximum distance of the upward movement of the locking rod 506. When the first sliding sleeve 504 and the second sliding sleeve 505 are prevented by the positioning ring 503, the locking rod 506 moves to the maximum height, and the hook 507 can pass through the locking groove 301 by horizontal rotation. The other side limits the locking rod 506, so that the locking rod 506 is limited in the area of the mounting disc 501 and is located below the connecting disc 4, which is convenient for the staff to reach by hand.

[0030] After the first sliding sleeve 504 and the second sliding sleeve 505 are closed and connected with each other, they can slide up and down on the vertical rod 1, push the locking rod 506 upward, and the locking rod 506 rises between the straight plugs 3. When the first sliding sleeve 504 and the second sliding sleeve 505 are prevented from moving by the mounting disc 501, the locking rod 506 is rotated to the side, the hook 507 on the locking rod 506 passes through the locking groove 301, and the locking rod 506 is released. The first sliding sleeve 504, the second sliding sleeve 505 and the locking rod 506 naturally fall under the action of gravity. When the locking rod 506 falls to the lowest part of the locking groove 301, the first sliding sleeve 504 and the second sliding sleeve 505 stop moving downward, the hook 507 is located at the side of the straight plug 3, and the locking rod 506 is prevented from being separated. When the horizontal rod 2 is accidentally hit upward, the straight plug 3 moves upward in the straight plug groove 401, and the locking rod 506 moves synchronously. When the locking rod 506 contacts the connecting disc 4, the movement of the straight plug 3 is prevented, so that the straight plug 3 cannot be completely separated, the horizontal rod 2 is prevented from being completely separated, and the safety during construction is improved.
